[Continued on next page] = (54) Title: SCHEDULING REQUEST TRANSMISSION TO REQUEST RESOURCES FOR A BUFFER STATUS REPORT (57) : A UE may receive a directional synchronization subframe from a base station and transmit a scheduling request to the base station during a time period based on the directional 105-b synchronization subframe. The scheduling request may enable a base station to grant the UE resources to send a buffer status re- port (BSR). The time period may be associated with a random access channel (RACH) time period. The UE may also transmit a scheduling request within a frequency region of the RACH time 405 period. The scheduling request may be transmitted based on a re - ceived indication of a set of subcarrier, a cyclic shift, or a se- quence index. In some examples, the resources used by the UE to send the BSR may include physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) re- sources.
